NOZZLE SUPPORT FOR SPRAY BOOMS Loren E. Bartling, Detroit, Mich.,assignor. t V v y V Dearborn Motors Corporation, HighlandPark,Mich.,acorporation of Delaware .I I 1 Application March 1,1050,SerialNo.1 47,070 i 1 Claim. 1

This invention relates to an improved agricultural sprayer, andparticularly to a simple, economical and efiective nozzle support forconnecting a spray producing nozzle member to a fluid conducting sprayboom.

In most agricultural sprayers, it has been customary to employ arelatively long, hollow boom which functioned not only to support aplurality of nozzles in spaced relationship therealong, but also toconduct the fluid to be sprayed to such nozzles. Obviously, each of thespray producing nozzles must be firmly mounted on the boom in fluidsealed relationship relative thereto, and heretofore there has not beena satisfactory device for accomplishing the removable mounting of thenozzles on the boom and the establishment of the fluid sealedrelationship of the nozzles with the fluid conduit defined by theinterior of the boom.

Accordingly, it is an object of this invention to provide an improvednozzle support for spray booms, characterized by unusual simplicity andeconomy of construction.

A particular object of this invention is to provide a nozzle supportmember of generally boltlike configuration, having its shank portiontraversing a tubular spray boom and clamped thereto in sealedrelationship by a fastening device cooperating with the projecting endof such shank portion, and defining a fluid passage extending to theaxial end of the nozzle support, which axial end may also accommodate afiltering element and a spray producing nozzle.

The specific nature of this invention, as well as other objects andadvantages thereof, will become apparent to those skilled in the artfrom the following detailed description, taken in conjunction with theattached sheet of drawings on which, by way of preferred example only,is illustrated one embodiment of this invention.

On the drawings:

Figure 1 is a side elevational view of a portion of the spray boomshowing a nozzle support embodying this invention assembled thereto.

Figure 2 is a sectional View taken on the plane 22 of Figure 1.

As shown on the drawings:

The numeral I0 indicates a portion of a, conventional spray boom orconduit formed of metal or similar relatively rigid material anddefining a fluid conduit Illa. 'At one or more locations along thelength of the boom I '0, a, transverse hole Illb is provided in the wallof the boom I0, and such hole is employed to mount a nozzle support I Iconstructed in accordance with this invention.

The nozzle support I I may be conveniently described'as being ofbolt-like configuration, i. e., it has a cylindrical shank portion I lafitting snugly in the hole Illb of the boom .IIland. the end of suchshank portion projects outwardly beyond one side of the boom I I] and isthreaded to receive a nut I4. In addition the nozzle support II has anenlarged cylindrical head portion Ill). The nozzle support II may thenbe conveniently secured to the boom III in fluid sealed relationshipthrough the provision of a rubber sealing washer I2 and a metal washerI3 which fit snugly around the shank portion Ila and are disposedintermediate the head portion III) and the wall of boom III, while anadditional rubber washer I2 and metallic washer I3 are providedintermediate the nut I4 and the adjacent wall of boom I0. Obviously bytightening the nut I4, the resulting compression of the rubber washersI2 will produce a fluid sealed joint between the nozzle support l I andthe fluid conduit Illa defined by the bore of boom III.

The nozzle support II is provided with a fluid passage I I0 whichcommunicates between one axial end of the nozzle support II and theinterior of the boom I0. For example, the fluid passage I I0 mayconveniently comprise an axial hole IId drilled into the nozzle member II through the head portion IIb and terminating within the shank portionI la at a point well within the interior of boom ID. A transverse hole IIe is then drilled through shank portion Ila to provide fluidcommunication between the axial hole Nd and the bore Illa of the boomI0. Hence, by forming or mounting a spray producing member in the headend of nozzle support I I, it is apparent that the fluid contents of theboom II] can be conveniently discharged as a spray through the fluidpassage provided by the nozzle support II.

If desired, the outer end of the axial hole IId may be counterbored asindicated at II) to provide a chamber in which may be convenientlymounted a suitable filtering element I5, here indicated as a cylindricalplug formed of metallic gauze. A spray producing nozzle I6 is securedacross the end of head portion III) in any convenient manner, such forexample, by a collar I"! which is threadably engaged with threads I lgformed on the end of head portion III). The nozzle member I6 defines anorifice Ilia which is suitably shaped so as to produce a spray dischargeof fluid applied thereto.

From the foregoing description, it is apparent that this inventionprovides an unusually economically manufacturable construction of anozzle support, which may not only be conveniently mounted on a sprayboom in fluid sealed relationship, but may be equally convenientlyremoved from such spray boom for replacement, cleaning or repairpurposes.

It will, of course, be understood that various details of constructionmay be varied through a wide range without departing: fromthe principlesof this invention; and it is, therefore, not the purpose to limit thepatent granted hereon otherwise than necessitated by the scope of theapev pended claim.
